I'm guessing that car is "drive-by-wire" via the throttle, which has not been an actual cable in most cars for decades at this point. Steer-by-wire is indeed just the cybertruck at this point afaik.

electronic throttle body controls are extremely common, yes. but they don’t have any downside to driving feel, so i don’t think it would fit what the GP was referring to.

Parent nailed it. I feel lag every time I hit the pedal and it messes with me.

It's cables for me but I'll settle for linkage.
